Be aware that the typical high temperature paint will shift colors slightly when hot. White when cold could equal yellow when hot.

From my experiences with VHT (admittedly over 40 years ago), it is very susceptible to permanent marks left by greasy finger prints, dripped or sprayed oil, or just about any other contaminant found in an engine compartment.

i understand...i'm still looking at all options.....just love them old vintage trans am cars .....i know VHT carries high temp paint for headers....also looking at Rustoleum Stove paint which resists up to 1500 degrees and got different colors tooo......i know alot guys do jet hot coatings and soo forth but i just like the old school painted look.....or maybe i'm just crazy
